Over the last decades, gold nanoparticles (AuNPs) have proven to be remarkable tools for drug delivery and theranostic applications in cancer treatment. On other hand, Pt(IV) prodrugs been employed as an interesting alternative more common Pt(II) complexes, such cisplatin, chemotherapy. Searching design image-guided nanocarrier deliver selectively tumors expressing gastrin releasing peptide receptor (GRPR), we synthesized small core AuNPs carrying a thiolated DOTA derivative, GRPR-targeting...
